Peak-End Theory
Clients don't remember your entire class.
They remember two moments: the peak and the ending.
Everything else fades.
What it is
Peak-End Theory is the psychological principle behind how people store experiences. Nobel laureate Daniel Kahneman proved this across decades of research. At CORE40, we've pressure-tested it across 5,000+ classes.
The FLATLINE
Most Lagree classes are what I call a FLATLINE: same energy start to finish, no intentional peak, forgettable ending. The client leaves feeling like they worked hard. They don't feel transformed. They don't rebook with urgency. They don't tell anyone about it. The coach missed the moment. The studio missed the superfan.
The Focus 20
At CORE40, we solve this with THE FOCUS 20: the final 20 seconds of every exercise are intentionally designed as a psychological and physical peak, followed immediately by the transition. Clients finish each set feeling successful, capable, and motivated to return. We close every class on an intense high. The ending is engineered, not accidental.
Presence is everything
"It's not about following your pre-programmed script. It's being able to adapt instantly in real time to what's actually happening in class."
"They remember the peak. They remember the finish. Design both intentionally."
"The peak is where identity shifts."
"For what comes after, the ending is crucial."
"They don't remember the cues; they remember how you made them feel."
"Presence builds super fans."
"The ending matters more than the duration."
